Cold storage facilities are an essential component of the food industry. Virtually every piece of food that hits the American dinner table spends some time in climate controlled warehouse. Not surprisingly, there's a lot more to these cold storage warehouses than just a cold room. Behind every piece of food sitting on a pallet is a complex logistics chain that includes transportation, delivery and storage.

Air Changes - The number of times the volume of air is replaced per hour in a stationary or mobile climate controlled container.

Back Up Generators - Every cold storage facility should have an emergency plan for dealing with power outages. These plans normally rely on a set of diesel powered generators that kick in when the primary power source goes out. Anyone storing perishable food items in a commercial facility should inquire about the company's back up power plan.

Cold storage warehouses and containers are located all over the United States. After all, many people and businesses require these climate controlled storage units in order to transport and house goods. As you may have seen before, there are mobile containers or semi trailers that can be used for hauling perishable foods. The refrigerated trailers keep the internal temperature cooled to a certain degree so that no food gets spoiled during transport. Then the foods can be stored in a room or freezer unit until they are shipped to a grocery store or supermarket location.
Countless food companies relay on cold storage facilities and climate controlled warehouses. These units are typically insulated in order to prevent the inside atmosphere from getting hot. Perishable food products are also packaged in a certain way so they do not get damaged. Some storage units and mobile trailers even have backup generators that ensure climate control. The logistics may vary depending on the type of product or perishable food being dealt with. In the US alone, there are cold storage warehouse facility locations rented daily. These warehouses are designed for both delivery and pickup access, which makes it easy for truck drivers to access them. As you likely know, food products are taken from storage containers and warehouses, and distributed to stores daily.
